System and method for dynamic power savings for short range wireless systems

Abstract

A method ( 100 ) and system ( 11 ) of dynamic power savings for a shorter range wireless connection based on service conditions for a longer range wireless connection can include the monitoring ( 102 ) a latency requirement for the longer range wireless connection based on service conditions and dynamically modifying ( 104 ) a reconnect time for the shorter range wireless connection with a change in the latency requirement for the longer range wireless connection based on change in service conditions. The latency requirement for the longer range wireless connection can be based on changes in communication modes for the longer range wireless connection. The communication modes can be a dispatch audio mode, an interconnect audio mode, or an out of service mode for example. The step of dynamically modifying the reconnect time can optionally include adjusting ( 106 ) the reconnect time as service conditions change to meet a most critical timing to be encountered.
